It is an USB HID device, so it is auto-detected and supports hot-swapping.
|
||||
|
||||
Flickering values in the rail voltage levels can be an indicator for a failing
|
||||
PSU. The driver also provides some additional useful values via debugfs, which
|
||||
do not fit into the hwmon class.

98h for socket 0 and 90h for socket 1, but it could vary based on hardware

Description
|
||||
-----------
|
||||
|
||||
The SBI temperature sensor interface (SB-TSI) is an emulation of the software
|
||||
and physical interface of a typical 8-pin remote temperature sensor (RTS) on
|
||||
AMD SoCs. It implements one temperature sensor with readings and limit
|
||||
registers encode the temperature in increments of 0.125 from 0 to 255.875.
|
||||
Limits can be set through the writable thresholds, and if reached will trigger
|
||||
corresponding alert signals.

* for now that uses non-zero values)
